Frequently Asked Questions

What is the 'Killer Key of Death'?

The 'Killer Key of Death' is a specialized tool designed to permanently disable a lock. Once inserted into a compatible lock (like Schlage or Kwikset), it becomes stuck, preventing any other key from being used and rendering the lock inoperable.

How does the Killer Key work?

The Killer Key works by engaging an internal hooking mechanism within the lock cylinder. After insertion, a slight pull back causes the key to lodge itself permanently, effectively breaking the lock and preventing removal.

Are Killer Keys universal for all locks?

No, Killer Keys are brand-specific. You must ensure you have a Killer Key designed for the specific lock brand, such as Schlage or Kwikset, for it to function correctly.
